atented May l2, 1931V ateos ERNESI El. 0F DETROIT, MICHIGAN CLUTCH FACING- Application filed January 31, 1929.. Serial No. 336,347.

rlhis invention relates to clutch facings.`

In clutch discs of the type which are adapted to be distorted when the clutch is engaged, it is desirable to have a clutch disc facing which can be readily distorted to conform to the configurationv of the distorted disc. I-Ience, it is the object of this invention to present a clutch disc facing which is scarfed whereby the disc facing is divided into a plurality of parts whichv are connected in hlnged relation'so that the disc facing is readily distortable with the above mentioned type of distortable clutch disc.

In the drawings: Fig. 1 is an elevation of the scarfed facig. 2 is a section along line 2 2 of Fig. 1.

Fi 3 is a cross sectional view showing the acing mounted` u on a fiat clutch disc.

Fig. 4 is a view o the facing mounted upon a clutch disc of the type described in my Patent 1,571,747.

Figs. 5 and 6 are cross sectional views of the facing mounted upon adisc of the double truncated conicall type described in my co-pending application, Serial No. 334,- 621, filed January 24;, 1929. The distortion of the disc in Figs. 4 to 6 is exaggerated for descriptive clearness.

Referring more particularly to the drawings, the disc facing is designated 1 and has the holes 2 which are adapted to receive any suitable means such as rivets for securing the facing to the clutch4 disc. lhe facing is preferably continuous and scarfed concentrically as at 3. g p

In Figs. 3 to 6, the disc facing isshown mounted upon various types of clutch discs. In these figures, the flywheel, which constitutes in this instance the driving disc, may be designated 4, and the pressure plate 5.

In Fig. 3, the facing is mounted upon a fiat disc 6 which is of the type that is fixed upon the driven shaft, and hence, must be distorted by the pressure plate 5y when the clutch is engaged. Owing to the scarfed portion 3 of the disc facing 1, the facing will readily conform to the distorted disc 6. In Fig. 4:, the facing 1 is shown mounted upon clutch disc 7 of the truncated conical type described in my Patent No. 1,571,747 which has an outersection 11 that is adapted to be distortedby pressure plate 5 when the` clutch is let in. Owing .to the concentrically scarfed area 3, the disc facing 1 is better adapted to adjust itself to the configuration of the distorted section 11 of the disc 7 when the clutch is engaged.

.In Figs. 5 and- 6,'the facing is shown4 mounted upon the double truncated conical type of. clutch disc which is described in `my co-pending application, Serial No. 334,-

Hence, it is vobvious that the disc facing n will hinge'about this scarfed area Iand that it may be more readily distorted to conform to the clutch disc when the clutch is engaged. Further, this hinged relation between the parts of the facing gives substantially all the benets of a facing composed of a plurality of separate parts and the still further important benefit of obviating the necessity of handling a plurality of parts during the assembly of the facing toA the clutch disc. Fig. 5 discloses a facing in which the parts' 9 and 10 have a hinging action. Afterth'e facin has been used a while, it may break all o the way through as shown in Fig. 6, in lwhich case the facing is divided into a plurality of separate parts.

It is evident from the above description that I have produced a clutch disc facing which will readily conform to the conv figuration of a distortable clutch disc and which may be eliciently assembled to the clutch disc.

What I claim is:

1. For a distortable clutch disc, va circumferentially scarfed facing. f-

2. For a distortable clutch disc, a concentrically scarfed'facing.

3. For a distortable clutch disc, anl

initially scarfed facing arranged to readily conform to the configuration of the distortable disc.

4. For a disc-like distortable clutch disc, a facing having a plurality of hinged parts.

5. A facing for a clutch having opposed scarfs yfor a dividing said facing into a plurality of integral parts for facilitating the action of the disc in packing whereb the facing can 'be assembled to' the clutc disc as a unit.

6. Facings for a clutch having opposed vconcentric scarfs'which divide the facings into a plurality of integral concentric parts whereby the facings can be assembled to the clutch disc as a unit. Y

7. A facing for al clutch comprising a plurality of parts having an integral scar-fed breakable connection whereby the 'parts may be initially assembled to the disc as a unit.

In testimony whereof I have affixed lmy signature.
